ABSTRACT:
A roller for paper or foil sheet handling machines such as printing presses comprises a cylinder consisting of fiber reinforced plastic material including alternate layers of circumferentially wound fibers and helically wound fibers. The helically wound fibers are arranged in groups of strings which are spaced from one another so as to form rhombus-shaped depressions in the surface of the cylinder, thereby providing rollers of relatively low masses but high strengths which have surfaces capable of firmly engaging the paper or foil sheets.
